python - 如何在 Anaconda 中使用 Python Dbus 绑定(bind)

Question

我正在尝试在 Anaconda python 环境中安装 dbus，但我很挣扎。

这是我收到的错误消息:

e@gateway:~$ python
Python 3.5.4 |Anaconda custom (64-bit)| (default, Oct 13 2017, 11:22:58) 
[GCC 7.2.0] on linux

>>> import dbus
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/e/anaconda3/lib/python3.5/site-packages/dbus/__init__.py", line 77, in <module>
    import dbus.types as types
  File "/home/e/anaconda3/lib/python3.5/site-packages/dbus/types.py", line 6, in <module>
    from _dbus_bindings import (
ImportError: /home/e/anaconda3/lib/python3.5/site-packages/_dbus_bindings.so: undefined symbol: _Py_ZeroStruct
>>> 

以下是我认为可能会被问到的一些输出:

e@gateway:~$ conda install dbus

DBus 在系统 python 上运行良好，但不适用于 Anaconda Python。

python 2.7:

e@gateway:~$ which python
/usr/bin/python
e@gateway:~$ python

>>> import dbus
>>> 

python 3.5:

e@gateway:~$ which python3
/usr/bin/python3
e@gateway:~$ python3

谁能帮帮我？我是否遗漏了一些明显的东西？

提前致谢。

我有类似的问题，很少有 dbus 和 python don't work well out-of-the-box .共识似乎是您需要系统级安装(即 apt-get)才能让 dbus 工作。我相信您看到的 /home/e/anaconda3/lib/python3.5/site-packages/_dbus_bindings.so: undefined symbol: _Py_ZeroStruct 错误与此直接相关。

conda install dbus 没有向 ~/anaconda3/lib/python3.6/site-packages 添加任何内容，而是似乎在 中安装了一些可执行文件~/anaconda3/bin/ like dbus-run-session, dbus-daemon 等。当你分析dbus tarball的内容时，这有一些意义https://anaconda.org/conda-forge/dbus ，因为它都是 C 文件和可执行文件。我不确定它应该是 dbus python 模块，但我可能是错的。

编辑:

我搜索了 conda 存储库，发现一些人上传了一个版本的 dbus-python，大概是他们编译和安装的。我试过 this one通过以下方式在 py3.6 conda 环境中输出:

conda install -c scottwales dbus-python

然后我可以导入 dbus。这是一种 hacky 方法，不应该在生产中使用，我建议听听下面是 Carlos Cordoba 的帖子。但是，如果您现在需要解决方案，请搜索一些用户 conda 包或尝试自己编译库。
